When you say "put under bridge", where are the packets generated? Do you generate
the packets on the nodes on which batman-adv runs, or are you receiving/forwarding
packets from other interfaces (eth0, wlan0...)?

In this case, the iptables rules might not apply correctly - you can check by
snooping the traffic on bat0 (using tcpdump/wireshark) and see if the DSCP field
is set according to your rules. If not, the iptables call might not be effective
and you might want to check bridge-nf-call parameters (see the top of [1] for
explanation).

If the DSCP field is set correctly but batman-adv still ignores it, please let me
know. :)

Cheers,
	Simon
